We theoretically studied the effect of a metal dimensions on the propagation loss of surface plasmon polaritons (SPPs) in a metal-semiconductor-semiconductor (MSS). The propagation loss of surface plasmon polaritons (SPPs) is studied at the interfaces between metals and active media .The propagation loss is calculated at the wavelength λ=1550nm for different widths and thicknesses of a gold layer. Also it has been observed the variation of the propagation loss with the height of the AlxGa1-xAs which is between the gold film and high refractive semiconductor. We analyze metal-semiconductor-semiconductor (MSS) waveguide by using the effective-index method (EIM) and the finite-difference-time-domain (FDTD) methods.
